Assalammualaikum, I am not sure if my ancestor is related Prophet Muhammad (peace be upon him) . From my uncle story , ancestry of my mother side is traced back to 14th century . Two missionaries from arab country ( i am sure which one ) came to Malacca (a historical town in Malaysia ) and tought the first sultan of Malacca about Islam and he became interested and embraced Islam . According to my uncle , these arabs were my ancestor . My family used to use syaid or syed name but stopped it during british time ( around 1930s) for security reasons.I wonder if in your record contains information about two arabs travelling to Malacca during 14th or early 15th century . Some people said , these two people were descendant of Prophet , i am not sure which one but i hope you could find me some information .
